| Area Forecast Discussion National Weather Service New Orleans LA 636pm CDT Tuesday April 23 2024 Long Term (Thursday through Monday night) Issued at 145pm CDT Tuesday April 23 2024 The long term period starts with the stalled front just to our north and east. Again, ahead of the front there could be some morning fog, however, as pressure gradient tightens between a high to our east and a strengthening surface low over the high plains, this will become less of a concern late in the week. The northwesterly flow on the eastern periphery of a ridge axis over Texas will eventually transition to a southwesterly flow by Friday as a strong H5 trough begins to amplify over the central plains. This trough will suppress the upper ridge across the Gulf of Mexico...as such the heigheights and thicknesses will increase across our region allowing for the warming trend to continue before balancing out later in the weekend or early next week. A cold front stalls upstream early in the weekend close to the Sabine River and ArkLaTex region. This will likely keep most rain chances up that way this weekend. A strong mid and upper level impulse amplifies and takes the same path roughly as the prior weaker impulse. This feature looks to move the aforementioned stalled frontal boundary eastward toward our area early next week. As it does, we'll likely start seeing an uptick and scattered showers and thunderstorms, especially across our western tier counties/parishes late Monday or early Tuesday. Still low confidence in timing and precipitation probs, but we'll fine tune going into the weekend. (Frye) Marine Issued at 145pm CDT Tuesday April 23 2024 Fairly benign marine conditions early on in the forecast period. Onshore flow is anticipated to develop and gradually strengthen through the week. During the afternoons, winds could be enhanced over the MS Sound and Tidal Lakes. May need short fused Cautionary headlines or even SCA (Small Craft Advisory) if the forecast trends up even just slightly. The pressure gradient increases on Friday and through the weekend where Cautionary headlines and/or SCAs (Small Craft Advisories) look to be a safe bet across the local waters.
